Before Faith Junker was adopted at age 6 by J and Tiffany Sudela-Junker, she and her little brother Jonah lived with their drug-addicted birth mother in an Austin meth lab. They shared a room with a known pedophile. Jonah was burned by a meth pipe. Faith begged neighbors for food.

After the Junkers adopted the siblings through Child Protective Services, they discovered that Faith suffered from post traumatic stress disorder and reactive attachment disorder — difficulty expressing and receiving affection — as a result of her early childhood trauma.

The family's story is the subject of a documentary, “My Name Is Faith,” that will be at screened 7 p.m. Saturday at the Alamo IMAX Theatre Rivercenter. Attachment & Trauma Network and CALO, a treatment center for adopted teenagers who are struggling, are presenting the screening. Tickets cost $10 at www.attachmenttraumanetwork.com.

“We're so glad we were able to make (the film),” Sudela-Junker said. “It brought this topic of kids who have trauma-impacted issues and challenges to the forefront.

“The film is not about treatment at all. It's really about what it feels like and the impact on a family to deal with this level of trauma.”

After attending a family camp in Canada run by therapeutic parenting specialist Nancy Thomas, the Junkers started their own camp, Camp Connect, and ran it for two years. “My Name Is Faith” follows the Junkers and other struggling families at Camp Connect in 2008 and 2009.

“You don't go and all of a sudden your kids are fixed and you're the Cleavers now,” Sudela-Junker said. “It is a lifelong process with these kids, but the thing that's so great is that you're surrounded by other families and a team of people who have trained to do positive interventions and, for a while, your family's No. 1 goal is to connect and bond.”

The documentary also shows Faith confronting her birth mother, Andrea.

“My daughter has strength from within beyond her years,” Sudela-Junker said. “Her being able to do that and handle it so well at her age empowered me to face my birth dad about my own issues.”

Faith is now 14 years old and able to connect with her family as they continue to work through issues. The Junkers live in Washington state and are focused on sharing their story. “My Name Is Faith” will soon be available on DVD and digital download, and plans for putting it on television are underway.
